A rubber ball is dropped and bounces vertically from a horizontal concrete floor. If the ball has a speed of 3.2 m/s just before striking the floor and a speed of 2.4 m/s just afte bouncing, what is the average force of the floor on the ball? Assume the ball is in contact with the floor for 0.15 s and the mass the ball is 0.14 kg. N
